Suggested abbreviation doesn't save characters

[fredrikr]

My game contains a lot of backslashes in strings, written as @@92. When compiling with -u the compiler says I should abbreviate this (Abbreviate "@@92";). When compiling the game, the compiler warns (correctly) that this abbreviation doesn't save any characters.

I used compiler version 6.36 with $MAX_ABBREVS=96.

It's clear that the optimizer is not taking @-escapes into account when computing scores.

I'm afraid the optimizer code is pretty opaque to me.

A related problem: abbrevations are matched in source text before @-escapes are resolved.

This means that Abbreviate "a@@61b"; will not match in the string "a=b a@{3D}b", even though "=", "@@61", and "@{3D}" are all the same character.
