so, iiuc, when `IsPatSingleCase` is true, it means that any character in the
pattern can potentially be a head? could you add comment for this?
We also had a stricter condition for `Pat[P] == Word[W]`, but now `ut` would
get a bonus for `[u]nique_p[t]r`. Is this intended?
================
Comment at: clang-tools-extra/clangd/FuzzyMatch.cpp:273
if (WordRole[W] == Head) // Skipping a segment.
- S += 1;
- if (Last == Match) // Non-consecutive match.
- S += 2; // We'd rather skip a segment than split our match.
- return S;
+ return 1; // We want to keep it lower than the bonus for a consecutive
+ // match.
----------------
nit: move this comment into into own line now that it's taking two?
