That is, the function primarily doesn't act as a predicate, and in fact 
you never use it as such.

I just noticed that this function is identical to offset_1st_component() 
in sha1_file.c.

This is not a good location for this function because on Windows we get 
warnings about implicitly defined function isalpha() (which is hidden in 
the macro has_dos_drive_prefix).

I suggest to move offset_1st_component() to path.c, which would not be 
inlined anymore.
