[PATCH] D87667: [Support/Path] Add path::is_gnu_style_absolute

[Renato Golin via Phabricator via llvm-commits]

rengolin added inline comments.


================
Comment at: llvm/lib/Support/Path.cpp:704
+    // Handle drive letter pattern (i.e "c:") on Windows.
+    if (P.size() >= 2 && (P[0] && P[1] == ':'))
+      return true;
----------------
Neither `7:` nor `$:` are valid paths on Windows, I think.

Perhaps `std::isalpha(P[0])` would help.
