in Lua 5.2+, there's this string escape that allows you to put
"whitespace" (in particular, including newlines) in a string literal, by
skipping them entirely. now, unlike lua's long strings, python *does*
have escapes in long strings. however, sometimes you have help text:
"switches to toml config format. the old 'repos' " #cont
"table is preserved as 'repos_old'"
and... well yeah you can see what I did to make it work. if I used a
long string here, I'd get a newline and a bunch of indentation in the
middle.
so I propose a \z string escape which lets me write the above as shown
below:
"""switches to toml config format. the old 'repos' \z
table is preserved as 'repos_old'"""
(side note to avoid unnecessary comments: this help text refers to
database tables and migrations. it's not about lua tables.)
