[PATCH 1/5] make_absolute_path(): Do not append redundant slash

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

 



When concatenating two paths, if the first one already have '/', do
not put another '/' in between the two paths.

Usually this is not the case as getcwd() won't return '/foo/bar/',
except when you are standing at root, then it will return '/'.
