No, "hg global" doesn't mean anything AFAIK. "Global options" are
those that come between "hg" and the command (which is incoming, pull,
commit, etc.). "Specific options are specific to one command and apply
only to it.

You found something I didn't know, which is how to edit the config
file. Let's push the mq  example a little further:

hg --config extensions.mq=   qqueue -c newqueue
(edit some file in the tree)
hg --config extensions.mq=   qnew -U -m 'fix build eror in somefile.c'
hg --config extensions.mq=   qpop

In this case the --config is not permanent. Your method is more
elegant. This way might be more suitable to enable or disable paging
for the duration of one command. Also, let's say, to know if you want
to enable some specific extension, because its help is only accessible
if theextensio is enabled. To know what mq does, then if it is
disabled you would need

hg --config extensions.mq=   help mq
