- * Definition of wildcard syntax:

- * 

- *  - * matches any sequence of characters, including zero.

- *  - ? matches exactly one character which can be anything.

- *  - [abc] matches exactly one character which is a, b or c.

- *  - [a-f] matches anything from a through f.

- *  - [^a-f] matches anything _except_ a through f.

- *  - [-_] matches - or _; [^-_] matches anything else. (The - is

- *    non-special if it occurs immediately after the opening

- *    bracket or ^.)

- *  - [a^] matches an a or a ^. (The ^ is non-special if it does

- *    _not_ occur immediately after the opening bracket.)

- *  - \*, \?, \[, \], \\ match the single characters *, ?, [, ], \.

- *  - All other characters are non-special and match themselves.

- * Some notes on differences from POSIX globs (IEEE Std 1003.1, 2003 ed.):

- *  - backslashes act as escapes even within [] bracket expressions

- *  - does not support [!...] for non-matching list (POSIX are weird);

- *    NB POSIX allows [^...] as well via "A bracket expression starting

- *    with an unquoted circumflex character produces unspecified

- *    results". If we wanted to allow [!...] we might want to define

- *    [^!] as having its literal meaning (match '^' or '!').

- * The wildcard matching technique we use is very simple and

- * potentially O(N^2) in running time, but I don't anticipate it

- * being that bad in reality (particularly since N will be the size

- * of a filename, which isn't all that much). Perhaps one day, once

- * PuTTY has grown a regexp matcher for some other reason, I might

- * come back and reimplement wildcards by translating them into

- * regexps or directly into NFAs; but for the moment, in the

- * absence of any other need for the NFA->DFA translation engine,

- * anything more than the simplest possible wildcard matcher is

- * vast code-size overkill.

- * 

- * Essentially, these wildcards are much simpler than regexps in

- * that they consist of a sequence of rigid fragments (? and [...]

- * can never match more or less than one character) separated by

- * asterisks. It is therefore extremely simple to look at a rigid

- * fragment and determine whether or not it begins at a particular

- * point in the test string; so we can search along the string

- * until we find each fragment, then search for the next. As long

- * as we find each fragment in the _first_ place it occurs, there

- * will never be a danger of having to backpedal and try to find it

- * again somewhere else.
