c++.stlsoft - Idea for filesystem_traits

There's a function in shlwapi (windows, of course) called PathCanonicalize, 
which parses "." and ".." parts of a path, could that turn out to be useful 
for filesystem_traits?

Nice idea. I've got something similar in the Synesis libs that I did
many years ago, and have been meaning to bring it into STLSoft for
yonks.

Actually, it's slightly different (and perhaps slightly better) in that
it - called deriverelativepath() - can deduce a relative path between
any two paths (and handles different drives on Win32). Internally, it
does all that canonicalisation stuff, so I guess the best thing would be
to split out the UNIX and Win32 implementations, and then split them
into the canonicalise and the derive-relative-path functionality

I don't think it should live in the filesystem_traits, since it's a bit
heavyweight. I'd probably have separate headers
unixstl_/winstl_filesystem_functions, or some such.

I'll try and get it into 1.8.3, or soon after.

Cheers

Great!

Actually, the original idea behind this suggestion, was precisely 
determining the relative path between two files...

The path classes in UNIXSTL and WinSTL now have implementations of their 
canonicalise() methods, which do this.
