Verbatim paths with no plain equivalent are passed through unchanged.

+### Hooks receive non-verbatim paths on Windows
+
+**Summary**
+
+On Windows, the `{path}` and `{root}` values substituted into `on-file` and
+`parsed()` commands could carry the verbatim prefix (`\\?\C:\...`,
+`\\?\UNC\server\share\...`). They are now the plain form. No signature
+changed. Output on Unix is unchanged.

+| `{path}` / `{root}` on a drive | `\\?\C:\data\a.txt` | `C:\data\a.txt` |
+| `{path}` / `{root}` on a share | `\\?\UNC\server\share\a.txt` | `\\server\share\a.txt` |
+
+A verbatim path whose plain spelling would name a different file (a reserved
+device name, a trailing dot or space, a path of 260 or more UTF-16 units, or a
+`\\?\GLOBALROOT` / `\\?\Volume{...}` form) is still passed verbatim.

+### Windows on-file arguments reach MSYS children unexpanded
+
+**Summary**
+
+On Windows, every argument of an `on-file` command is now passed double-quoted
+by the MS C-runtime rules. An MSYS/Cygwin child (Git for Windows' `sh`,
+`printf`, `cat`) previously glob- and brace-expanded any argument without a
+space or tab; it now receives the argument as written. MSVCRT children parse
+the same values as before. No signature changed, and Unix is unchanged.
+
+**Required changes**
+
+_None._
+
+**Deprecations removed**
+
+_None._
+
+**Behavior changes without code changes**
+
+| Surface (Windows, MSYS child) | Before | After |
+|---|---|---|
+| `on-file = "printf '[{}]'"` | child prints `[]`, zero rows | child prints `[{}]`, one row |
+| an argument `*.txt` | expanded to matching files | the literal `*.txt` |
+
+A config that relied on an MSYS child expanding a glob in its argv must ask
+for a shell explicitly: `sh -c 'cat *.txt'`.
+
+**Verification**
+
+```toml
+[[table]]
+name = "t"
+ddl = "CREATE TABLE t (n INTEGER)"
+glob = "*.txt"
+on-file = "printf '[{\"n\":1}]'"
+```
+
+```bash
+dirsql query "SELECT n FROM t LIMIT 1" -c .dirsql.toml
+# [{"n":1}]
+```
