I'm running Linux 64-bit, build 2177.
In a plain text file (Syntax checked is "Plain Text") with Word Wrap checked and Word Wrap Column set to 'Automatic', I'm getting the occasional incorrect word wraps - where the edge of the window falls at the end of a line, ST will break a line between the last character of the last word and a period, so that in the wrapped line the period is the first - and sometimes the only character in the wrapped line. Given the line
Now is the....country.
Sometimes ST will wrap it like this:
Now is the....country
ST will also break at a quote character, leaving the quote as the only character on the wrapped line, thusly: Given the line "Now is the.....country." it will wrap like this:
"Now is the....country.
or even like this:
"Now is the....country
." Now is the...
This is a bit unusal. Most wraps in ST occur where and how you want, but these unusual cases will occasionally occur in a large file. Obviously, with plain text you don't want this kind of wrapping.
If you delete one or more characters from the line before one of these hanging wraps, the hanging character shows up in the previous line where it should - and also shows there isn't a blank character just before the period or quote that is causing the issue.
