It's not necessary to wait until there is built-in support for a new language.
For example, for Windows resource files, I have
*.rc diff=winres
in .gitattributes or .git/info/attributes and
[diff "winres"]
xfuncname =
"!^(BEGIN|END|FONT|CAPTION|STYLE)\n^[a-zA-Z_][a-zA-Z_0-9]*.*\n^[[:space:]]*([[:alnum:]_]+,
*DIALOG.*)"
in .git/config (the xfuncname is all on a single line). The first part
beginning at ! up to \n tells to ignore the specified matches. The other
parts separated by \n tell the things to put in the hunk header. You can
have "ignore" parts (with exlamation mark) and "take this" parts (without)
in any order that is convenient, as long as the last one is "take this".
