Subject: add -p: trap Ctrl-D in 'goto' mode
X-Git-Tag: v1.6.2-rc0~1^2~3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=68c02d7c462e1748578209346f050a587c040139;p=git.git

add -p: trap Ctrl-D in 'goto' mode

If the user hit Ctrl-D (EOF) while the script was in 'go to hunk?'
mode, it threw an undefined variable error.  Explicitly test for EOF
and have it re-enter the goto prompt loop.
