vc-hg.el : suggested patch to make hg command configurable

[Norman Gray]

Greetings.

Within vc-hg.el, the "hg" command is hard-wired as that precise  
string, rather than being configurable.  This is awkward for me at  
least, since I organise myself so that tools (potentially in multiple  
different versions) are kept out of /usr/local and similar, and paged  
in and out via per-shell adjustments to PATH.  But that means that hg  
typically isn't on the default path that emacs picks up.

Can I therefore offer the following rather trivial patch for vc- 
hg.el?  It works for me....

I got in touch with the original author of vc-hg.el, Ivan Kanis, who  
redirected me here.

Best wishes,

Norman
