Subject: Makefile: Simplify handling of python scripts
X-Git-Tag: v1.7.2-rc0~128^2~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=f733f6a0c690a3d5e399c438d4dc3f2307418171;p=git.git

Makefile: Simplify handling of python scripts

The sed script intended to add a standard opening to python scripts
was non-compatible and overly complex.  Simplifying it down to a set
of one-liners removes the compatibility issues of newlines.  Moving
the environment alterations from the Makefile to the python scripts
makes also makes the scripts easier to run in-place.

Specifically, the new sed script:

 - Alters the shebang line to use the configured Python.
 - Alters any os.getenv("GITPYTHONLIB") calls to use @@INSTLIBDIR@@ as the
   default.  This will replace any existing default or add a default if
   none is provided.
 - Replaces the @@INSTLIBDIR@@ placeholder with the directory git installs
   its python libraries to.

The last two steps could be combined into a single step, but is left
separate in case someone has another need for @@INSTLIBDIR@@ in their
script.
