":e test.hs" overwrites "test.hs" with emacs tags

[guest]

This is not really a bug but it can be confusing (and lead to loss of work) for programmers that use both Hugs and GHCi. In Hugs, :e filename opens filename in an editor. In GHCi 6.5 :e filename (short for :etags filename) creates an Emacs tags file, overwriting filename.

Some solutions:

• Use a different command to create emacs tags
• Make the command fail if the file already exists

Fair enough. We'll make ":e" invoke "edit" (not implemented yet), and ":etags" invoke etags. Abbrebiations as usual, so ":et" will do etags as well, and ":ed" would do edit.

Fixed: :e now pops up the editor, just like Hugs.

I didn't implement all of Hugs' :edit functionality, in particular we don't attempt to jump to a particular line in the file, but I've done enough to close this bug :-)
