Were it just exec_cmd.c, I would just have changed it to use _PATH_DEFPATH
from <paths.h> in preference to a make variable, as that should always give
an appropriate value for a correctly put-together system and is a sensible
place to treat as the central definition of 'default path'. However, in this
case it's needed in the shell script too and I don't think I can easily get
at _PATH_DEFPATH from there.
Having looked at this again, I think it's probably better to tackle the two
pieces separately. It would be cleaner to fix exec_cmd.c to use the correct
system-wide _PATH_DEFPATH from <paths.h> if possible, as in the following
patch, rather than introduce yet another make variable.
Similarly, looking more closely at what the path gets used for, I think
git-instaweb.sh is wrong to hard-code a default path anyway: it should
surely pass through the path inherited from the invoking user rather than
silently overriding it. I'll do a separate patch for that.
Cheers,
Chris.
