Allow digits in dynamic variables

[kirean@…]

Currently the syntax for dynamic variables is: "The syntax for dynamic variables is simple, any upper case word beginning with '$' is considered a variable." according to TracReports.

I would like that to be extended to also accepting digits, like $C2M.

I did try to use this now as in something like:

[snip]
AND (milestone=$MSONE or milestone=$C2M)

That did though break the query, without error message, resulting in zero hits. (bug?)

What do you think, could it be ok to extend this syntax?

This looks simple enough, and it does make sense. I'll add it to my to-do list.

#6728 asks for underscores in report variables.

Implemented in [7632].
