codespell ignores C/C++ tabs ('\t') in strings

[orbitcowboy]

I found out, that codespell gives wrong answers in case of a tab is used within a C/C++ string. For example:
test.c:

int main()
{
    std::cout<< "\tTest\n";
}

dict.txt:

ttest->test

Scanning with test.c with codespell gives a wrong result:

$ ../codespell.py dict.txt test.c 
test.c:3: tTest  ==> test

\n should also be ignored.

\t issue might have been resolved but I keep hitting this eldest ever issue with \n once in a while, e.g. on /tmp/1.c:

int main()
{
    std::cout<< "\tTest\nin here";
}

❯ codespell --version
2.2.2
❯ codespell /tmp/1.c
/tmp/1.c:3: nin ==> inn, min, bin, nine

codespell is language-agnostic. Handling escape characters would require to identify the type of each file and adapt --regex or --ignore-regex. A proof of concept could be a shell script identifying the type of each file and calling codespell with the proper --regex and --ignore-regex.
