racy git detection and lastmodified resolution in msysgit

[Matthias Sohn]

Shawn pointed out [1] that JGit truncates the lastmodified timestamp
cached in the index to 1s resolution
since msysgit discards the sub-second portion of the timestamp it gets
back from Windows. We are now
wondering why this can't be fixed in msysgit. A more precise racy git
detection could help to reduce the
chance to hit the racily clean case.

Hi,

I might misremember, but I think this was done to make the behavior
consistent with Cygwin. Unless there are valid concerns within the next
few days, I will gladly take a patch to fix this behavior to mimic JGit's
behavior.

Ciao,
