Don't require exactly one space before or after =

[arp242]

My postgresql.conf looks like this:

checkpoint_timeout = 30min   # Max. time between checkpoints; Default: 5min
max_wal_size       = 4GB     # Default: 1G
min_wal_size       = 256MB   # Default: 80M

It would fail to detect these keys as the tuneRegexFmt and tuneRegexQuotedFmt require exactly " = "; this changes that to "\s=\s" to accept any whitespace. It doesn't make any effort to write these spaces back – might be nice too, but I couldn't be bothered 😅

Also use ` for these strings so you don't need to double up the backslashes.
