/*$
* EN[pattern]$ -- Get list of files matching a glob pattern
*
* The EN command expands a glob \fIpattern\fP to a list of
* matching file names. This is similar to globbing
* on UNIX but not as powerful.
* A \fIpattern\fP is a file name with \(lq*\(rq and
* \(lq?\(rq wildcards:
* \(lq*\(rq matches an arbitrary, possibly empty, string.
* \(lq?\(rq matches an arbitrary character.
*
* EN will currently only match files in the file name component
* of \fIpattern\fP, not on each component of the path name
* separately.
* In other words, EN only looks through the directory
* of \fIpattern\fP \(em you cannot effectively match
* multiple directories.
*
* The result of the globbing is inserted into the current
* document, at the current position.
* A linefeed is inserted after every file name, i.e.
* every matching file will be on its own line.
*
* String-building characters are enabled for EN.
*/
/*
* NOTE: This does not work like classic TECO's
* EN command (iterative globbing), since the
* position in the directory cannot be reasonably
* reset on rubout with glib's API.
* If we have to perform all the globbing on initialization
* we can just as well return all the results at once.
* And we can add them to the current document since
* when they should be in a register, the user will
* have to edit that register anyway.
