How do you replace a line ending with a non-whitespace followed by zero or more spaces, by the matched non-whitespace followed by exactly two spaces, leaving the newline character intact?
Searching for this:
(\S)(\h*)$
will match. Replace with this:
\1 (?# two spaces after the one)
will leave the newline intact so that's OK. I was hoping it would discard the second match (\h* matches all whitespace except newline), but it doesn't. It leaves the second match, and adds two spaces in front of it.
Edit: This is an example. For clarity, [cr] is newline (CR + LF in windows), [sp] denotes 1 space, [2sp] 2 spaces, etc.
eggs[cr]
bacon;[2sp][cr]
[cr]
sausage.[3sp][cr]
should become
eggs[2sp][cr]
bacon;[2sp][cr]
[cr]
sausage.[2sp][cr]
Use case is writing markdown in Notepad++. I usually forget the two spaces marking <\br> I want to fix that with a regex search/replace. I know markdown is OK with two or more spaces, but still, it'd be cleaner to have just two. Without any additional search/replace of triple-or-more spaces, preferably.
