Here's an interesting bug: normally in a Bash session in MinTTY,
backspace and Ctrl+H both delete the previous character, as expected.
However, after running texconfig and returning to the shell, both the
backspace key and Ctrl+H appear to just print "^H" to the terminal.
It looks like this is genuinely the terminal trying to render a
backspace character, rather than just backspacing, given the following:
$ printf ^H | xxd
00000000: 08 .
(To get that, I typed "printf {backspace} | xxd".)
It's not clear to me whether this is Bash, MinTTY or texconfig that's
misbehaving. Ctrl+W to delete a word, Ctrl+R to get (for me) fzf's
history search, and using the up and down arrows to navigate history all
work. Running Vim, opening a new Bash shell from within the duff one,
or SSHing to another box has Ctrl+H working just fine within that
process, but the bugged behaviour resumes when I return to the original
Bash shell.
