Other paths in avrdude.upload.pattern are wrapped in double quotes, and this -P{serial.port} causes issues with some platforms. This allows serial port devices which include spaces and other characters. Without this fix a /dev/tty* or /dev/cu* device that includes a space in its name gets truncated when passed to avrdude. Error messages returned from avrdude are cryptic, and workarounds (symlinks) are prone to failure.
Fixes #3693
