Fixes "function" test against regular expressions

[matthew-dean]

In some browser engines (especially older versions of Webkit), this
test fails when the argument is a RegExp.

Fix tested and works with Adobe AIR.

Er, I wasn't sure how to make a new pull request. Fork the main repo again? These are technically my first pull requests, be gentle.

all good. I'll add a comment against the function check change once merged.

Out of curiosity, how would you get these into separate pull requests? What I did was delete my less.js fork, create a new one, make one change, commit and pull, make the other, commit and pull. But the second pull did both, because both commits were still technically different from the main repo.

Also, note that I didn't run tests other than my specific environment. I'll try to figure that out too, but I thought I could get the ball rolling.

A pull request is everything from one branch.. so when you committed the
second time it updated the pull request.

Its best to instead do each patch on a new branch.. e.g.
Git branch patch-1
Git commit
Git push (may need to set the remote here to create a new branch on the
server)
Git checkout master -b patch-2
Etc.

With 2 commits on master already, write down the sha hash codes from git
log, reset, branch and then cherry pick your commit on to each branch
seperately..

The tests are quite easy to install and run and you just get a yes or no on
the cli. I think the full instructions are on that development page.

Ah, thanks.
