Link to e.g. function name in a source file
### Description
Currently it is possible to link to a particular commit *and* a particular line #L123 in a source file, which is already great to guarantee the validity of the link, but won't help to point in future versions to e.g. the beginning of a function.
### Proposal
In Trac it is possible to point to `#/searchterm`, i.e. the first occurrence of `searchterm`.
Would be something similar thinkable for GitLab?
