   | 7400    | When setting the size of the pty for logging, check if       |
   | zmedico | stdout isatty rather than stdin.                             |
   |---------+--------------------------------------------------------------|
   | 7402    | For bug #186610, use `find ` to scan for config updates      |
   | zmedico | since `cd ` could fail and cause the cwd to be scanned.      |
   |---------+--------------------------------------------------------------|
   | 7405    | For --buildpkgonly, say "built" instead of "merged" in the   |
   | zmedico | "These are the packages that would be " message.             |
   |---------+--------------------------------------------------------------|
   | 7407    | For bug #186826, always show --newuse flags that trigger     |
   | zmedico | reinstallation even when not in --verbose mode.              |
   |---------+--------------------------------------------------------------|
   | 7410    | For bug #186480, while we transition to repository labels,   |
   | zmedico | avoid ? spam in the repository display by ignoring a missing |
   |         | repository label for an installed package. (branches/2.1.2   |
   |         | r7409)                                                       |
   |---------+--------------------------------------------------------------|
   | 7411    | For bug #186639, add more clarification about the            |
   | zmedico | relationship between /etc/make.profile/ and                  |
   |         | /etc/portage/profile/.                                       |
   |---------+--------------------------------------------------------------|
   | 7413    | For bug #186639, note that /etc/portage/profile/ supports    |
   | zmedico | all of the same file types that /etc/make.profile/ does,     |
   |         | except parent.                                               |
   |---------+--------------------------------------------------------------|
   | 7415    | For bug #185048, make emerge-webrsync honor http_proxy and   |
   | zmedico | ftp_proxy from make.conf.                                    |
   |---------+--------------------------------------------------------------|
   | 7417    | Handle 2 more cases where elog_process() needs to be called: |
   | zmedico | - binary install via pkgmerge() fails before reaching the    |
   |         | merge phase (pkg_setup dies) - doebuild() is called for the  |
   |         | merge phase but it dies before reaching the merge phase      |
   |---------+--------------------------------------------------------------|
   | 7419    | When the fetch phase fails inside doebuild(), create an      |
   | zmedico | eerror log since the mod_echo module might push the original |
   |         | message off of the top of the terminal and prevent the user  |
   |         | from being able to see it.                                   |
   |---------+--------------------------------------------------------------|
   | 7422    | For bug #186876, fall back it os.pipe() if pty.openpty()     |
   | zmedico | fails.                                                       |
   |---------+--------------------------------------------------------------|
   | 7424    | For pty logging, handle the EAGAIN error that is thrown from |
   | zmedico | fcntl when the slave end of the pty is closed on FreeBSD.    |
   |---------+--------------------------------------------------------------|
   | 7426    | Change "output" import to portage.output.                    |
   | zmedico |                                                              |
   |---------+--------------------------------------------------------------|
   | 7427    | For bug #187016, and env.d to the default USE_ORDER.         |
   | zmedico |                                                              |
   |---------+--------------------------------------------------------------|
   | 7428    | Update USE_ORDER docs for bug #187016.                       |
   | zmedico |                                                              |
