escape special symbols in lt-expand?

[unhammer]

Perhaps lt-expand should escape e.g. : as part of form/lemma (DJ:en:DJ<n><m><sg><def> looks like it has three fields). Similarly other reserved chars

I wonder if we shouldn't also be able to compile lt-expanded dictionaries. It could be just another optional format for lt-comp.

Reserved characters are still not escaped if they are part of a regular expression. Take the following example, which includes : and becomes difficult to process unless overly complicated regex is used. Otherwise, it looks like it has 4 fields:

__REGEXP__[.\?;:!]+:__REGEXP__[.\?;:!]+<sent>

It will now escape ^$/<>{}*@#+~: in regexes. Let me know if that list should be any different.
