| summary: Incorrect detection of reserved device names on Windows in path/filepath |
| description: |- |
| On Windows, The IsLocal function does not correctly detect reserved device |
| names in some cases. |
| |
| Reserved names followed by spaces, such as "COM1 ", and |
| reserved names "COM" and "LPT" followed by superscript 1, 2, or 3, are |
| incorrectly reported as local. |
| |
| With fix, IsLocal now correctly reports these names as non-local. |
