I assume you are talking about the function header that is displayed
in the hunk headers, and by default contains the nearest preceding
line that starts in the zeroth column.

Git can in fact be configured to recognize “functions” differently,
per file type. The gitattributes(5) manual page describes this:

   Defining a custom hunk-header
       […]

       First, in .gitattributes, you would assign the diff attribute for
       paths.

           *.tex   diff=tex

       Then, you would define a "diff.tex.xfuncname" configuration to
       specify a regular expression that matches a line that you would
       want to appear as the hunk header "TEXT". Add a section to your
       $GIT_DIR/config file (or $HOME/.gitconfig file) like this:

           [diff "tex"]
               xfuncname = "^(\\\\(sub)*section\\{.*)$"
