[PATCH 0/2] RUNTIME_PREFIX enhancements

[Johannes Schindelin <johannes.schindelin@gmx.de>]

When I ran "make" in msysGit's /git/, I was greeted by a pretty unfriendly 
message about a RUNTIME_PREFIX that could not be determined.

Not understanding the code in exec_cmd.c, I went back to a comment I made 
to one of the iterations of the RUNTIME_PREFIX patch series (back when I 
spent a considerable amount of time to understand the code), and turned it 
into a patch myself.

I hope you will agree that the code introduced in 1/2 is more 
understandable than what is removed in 2/2 in favor of the former.

The real meat comes in patch 2/2:

The problem is that Windows will look in the current directory before 
looking in the PATH when it tries to execute a program.  So it will find 
the executable C:\msysgit\git\git.exe and be unable to strip the suffices 
"libexec/git-core" or "bin".

I just added "git" (which should not hurt other users, but instead help 
them if they did not install Git but run it in-place).

Johannes Schindelin (2):
  Introduce the function strip_path_suffix()
  system_path(): simplify using strip_path_suffix(), and add suffix
    "git"
