Documentation:
Function used to determine an "atomic" element.
You can set it to `forward-char' to get char-level granularity.
Its behavior has mainly two restrictions:
- if this function encounters a newline, it's important that it stops right
after the newline.
This only matters if `smerge-refine-ignore-whitespace' is nil.
- it needs to be unaffected by changes performed by the `preproc' argument
to `smerge-refine-subst'.
This only matters if `smerge-refine-weight-hack' is nil.
