check if Filename matches Mask
if MatchExactly then the complete Filename must match, else only the

Filename matches exactly or is a file/directory in a subdirectory of mask.
Mask can contain the wildcards * and ? and the set operator {,}.
The wildcards will *not* match PathDelim.
You can nest the {} sets.
If you need the asterisk, the question mark or the PathDelim as character
just put the SpecialChar character in front of it (e.g. #*, #? #/).
Examples:
/abc matches /abc, /abc/, /abc/p, /abc/xyz/filename
but not /abcd
/abc/ matches /abc, /abc/, /abc//, but not /abc/.
/abc/x?z/www matches /abc/xyz/www, /abc/xaz/www
but not /abc/x/z/www
/abc/x*z/www matches /abc/xz/www, /abc/xyz/www, /abc/xAAAz/www
but not /abc/x/z/www
/abc/x#*z/www matches /abc/x*z/www, /abc/x*z/www/ttt
/a{b,c,d}e matches /abe, /ace, /ade
*.p{as,p,} matches a.pas, unit1.pp, b.p but not b.inc
*.{p{as,p,},inc} matches a.pas, unit1.pp, b.p, b.inc but not c.lfm
