I can attest from my impoverished Windows programming days that looking at

SomeErrorMessage about syntax 'c:\temp'
is not very helpful. There is zero visual indication that the \ and the t
are one character, not two. Changing that error message to:
SomeErrorMessage about syntax 'c:[\t]emp'
or
SomeErrorMessage about syntax 'c:\x07emp'
or something that shouts out, "hey! one character in this
location!" would be a good thing.
I like the \x07 solution.
So final question is do we take the easy road and change the repr for
str to always use hex or unicode escapes instead of simple
backslash-escapes (and then run for our lives), or do we just hunt down
and change the appropriate error messages for files (and possibly re) ?
Just a data point from a random programmer:
I like the \x07 solution for the error message as it draws attention to
the character at issue, but I also like to see \n, \t etc. in the result
of repr because it is more readable for the common cases.
