Remove incorrectly deprecated LANG_REC_SIZE phrase to not be confusing. Having only the *: none target is the same as deleting the phrase so this does not change the string order further. Put a note in the header in english.lang with some more info on deprecation of strings.

 # *WARNING*

 # If you want to add a new string, add it to the end of this file!
-# If you want to remove a string, just blank it, don't actually remove it!
+# Removing strings will break the numbering of strings in binary lang files and
+# voice files so instead of removing a unused <phrase>, change the desc field
+# to deprecated and either blank the strings or change them to
+# deprecated (whout quotes) and do *not* change the targets.

 # If you re-order things or remove entries, you must bump the binary language
 # file version number in both the 'genlang' tool and the language loader code.
