If a wildcard or completion expands to a file that begins with one or more dashes, prepend a ./ to it so that it doesn't get parsed as an option. Fixes #1519

wildcard_expand works by dividing the wildcard into segments at

each directory boundary. Each segment is processed separatly. All
|

except the last segment are handled by matching the wildcard
|

segment against all subdirectories of matching directories, and

recursively calling wildcard_expand for matches. On the last
|
|
segment, matching is made to any file, and all matches are
|
|
inserted to the list.
|
|
|
|
If wildcard_expand encounters any errors (such as insufficient
|
|
priviliges) during matching, no error messages will be printed and
|
|
wildcard_expand will continue the matching process.
