Fix typo

[staabm]

one less space per row in the dump can make a considerable difference in file-size

Not totally sure, but this seems to break tests when native mysqldump came with MariaDB.

[staabm]

I see. Should I adjust the tests or is it not acceptable?

[back-2-95]

If you can find the reason why this happens, please do. Tests generate native mysqldumps and then diff it with dumps done with the library. So it might be that native mysqldump gives two spaces there on some cases (mariadb?)

[staabm]

I will have a look. Please go ahead with the other things in the meantime and don't let it block a possible release

hmm I see the same bug in the origin mysqldump

https://github.com/mysql/mysql-server/blob/824e2b4064053f7daf17d7f3f84b7a3ed92e5fb4/client/mysqldump.cc#L2854

I don't see a way to get this fixed upstream

[staabm]

lets see whether I am able to contribute the change to mysql: mysql/mysql-server#524 ;).

I guess they will not accept the change, or it will take years to get into the wild... time will tell.
wish me luck.
