[issue1275] highlight extension is expensive to load

[Patrick Mézard]

New submission from Patrick Mézard <pmezard at gmail.com>:

Highlight extension disabled:

$ time hg help > /dev/null

real    0m0.117s
user    0m0.049s
sys     0m0.067s

Highlight extension enabled:

$ time hg help > /dev/null

real    0m0.316s
user    0m0.187s
sys     0m0.125s

There is a bunch of exceptions made to demandimport and monkeypatching probably
forces pygments modules to be loaded at extension load time. One solution may be
to split the extension in two files and monkeypatch with stub functions.
