cvsnt 2.0.37

Mainly a bugfix release.  After my email was down for a week I might have 
missed some bugs, so if yours hasn't been done then post again as it's likely 
it was overlooked.

2.0.38 will be a stable release (as I found a bug with the compressed deltas 
that means it's best that 2.0.36 is superceded pretty quickly).  Give this one 
a test - particularly any changes - and I'll get it stable by then (honest). 
I'm aiming to get that one out just after easter.

Changes:

* Read environment if user is 'SYSTEM' to try to determine real user.
* Renormalise the path sent to lockserver during 'edit' as that's a special case.
* Consolidation of the unicode routines (don't think I broke anything... 
passes my tests but it's worth trying it out to make sure).. leading to...
* Extended -k options to specify encoding.  This is a keyword based system (as
I was running out of letters of the alphabet and couldn't remember them all 
anyway).
	Generic form: -k{encoding} followed by the usual flags (k,v,l, etc.).
	Current supported encodings are:
		ucs2le,ucs2le_bom (alias for 'u'),ucs2be,ucs2be_bom

	eg.
		cvs update -k{ucs2be_bom} foo.txt


If I get time I'll implement ucs4.  shift-JIS is planned but I don't currently 
have enough info about that to give an implementation date.
