ACK 248d9a2fb1fab3dca595aa988f1fcd895904cf48

ax_... upstream, sec256* upstream, leveldb upstream please.

Very good finds! Can't believe I haven't found these myself :-)

The policy is not to fix typos in release notes/change logs, so please skip the changes made in contrib/debian/changelog.

One of the secp256k1 typos has been reported upstream by me: https://github.com/bitcoin-core/secp256k1/pull/440 :-)

ACK 248d9a2fb1fab3dca595aa988f1fcd895904cf48 modulo the above + @paveljanik:s comments

@ka7 The updated version is better but please also remove the changes made to:

build-aux/m4/ax_boost_base.m4
src/leveldb/
src/secp256k1/

These should be reported upstream instead :-)

@ka7 Thanks for a nice first-time contribution!

I used your misspell_fixer-tool to find 12 typos in the Swift project: https://github.com/apple/swift/pull/10710. That is quite impressive considering that the Swift project has had 218 merged typo fix PRs already. Prior to the run with your tool I believed the Swift repo to be at near zero typos (despite having 1.8 million lines of text in the repo) :-)

This can be compared to 14 typos in the Bitcoin project which has 400 000 lines of text in the repo (as measured by git grep "" | wc -l).

To compare:

• Your tool found one typo per 29 000 lines of text in the Bitcoin repo (400000/14)
• Your tool found one typo per 150 000 lines of text in the Swift repo (1800000/12)
