I'm using the following configuration to do that with Mercurial:

$ cat ~/.hgrc:
...
[extensions]
color =
pager =

[pager]
pager = less
quiet = True
attend = diff,status,log,qdiff,blame,annotate,pdiff,glog

$ echo $LESS
FRSXQ

That is, I'm using the flags "FRSXQ" with less. The following
configuration allows me to have pager + color in diffs for example.

Hope it helps,

 Jonathan
