This doesn't do everything possible to keep line lengths < LINE_BREAK, but does deal with "helptext=..." and long lists of "...","...", like the lists of actions in actions.ruleset and lists of "flags=" in units.ruleset. Not dealt with are "helptxt" strings within

flags={"name","helptxt"
class_flags={"name","helptxt"

in units.ruleset - there is only 1 instance in the supplied rulesets of a lengthy string. Also the Achievements in game.ruleset have strings for first_msg and cons_msg that could be long but there are no instances in the supplied rulesets.

The routine make_escapes() needed to be changed because as written it messed up the added new line chars. It was only called from entry_to_file() in registry_ini.c so I moved it from support.c/h to registry_ini.c and rewrote and renamed it.

Did a lot of testing - made sure running supplied rulesets thru new ruledit doesn't change appearance of helptext in the client help viewer. Also tested hacked input with edge cases and perverse strings. A token > 70 chars and no delimiters doesn't get split.

I discovered issue #1893 while testing, that issue and this one are independent and there's no need for a block.

Good catch on UTF-8, testing with "Agōgē of Sparta" shows a problem. Fixed the patch to test for high bit.

Yes backslash handling ('\\') is intentional. Otherwise inserting "\n\0x0A" doesn't work.

Yes tested savegames and client options files - the latter are unchanged, savegames wind up a little easier to read and still work OK.

Need different patches for different branches.
