Fix documentation of -I and -X options. These options apply to all names, not just to directories. In other words, you can do something like this: hg add -X 'f*' '*.c' and it will have the effect of "add all files matching *.c, except those starting with f".

+ hg init
+ echo This is file a1
+ hg add a
+ hg commit -m 'commit #0' -d '0 0'
+ ls
a
+ echo This is file b1
+ hg add b
+ hg commit -m 'commit #1' -d '0 0'
+ hg co 0
+ ls
a
