[PATCH v3 02/20] setup: add comment indicating a hack

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



'GIT_TOPLEVEL_PREFIX_ENVIRONMENT' was added in (b58a68c1c setup: allow
for prefix to be passed to git commands) to aid in fixing a bug where
'ls-files' and 'grep' were not able to properly recurse when called from
within a subdirectory.  Add a 'NEEDSWORK' comment indicating that this
envvar should be removed once 'ls-files' and 'grep' can recurse
in-process.
