--tx-broadcast-cmd is parsed incorrectly

[oriolpont]

the plugin's gui provides a window for custom options to be passed to bwt; however I've been unsuccessful with --tx-broadcast-cmd, it seems it seems the way the arguments are parsed breaks it.

Arguments at that input area get cut at every space, and --tx-broadcast-cmd requires at the very least a space, between the command and the {tx_hex} field, alas I find no way to escape the espace

Thanks for reporting this!

Back when I implemented thus, bwt had no arguments that could contain spaces so I didn't bother supporting them:

bwt-electrum-plugin/src/bwt.py

Lines 93 to 94 in ae06054

	# XXX this doesn't support arguments with spaces. thankfully bwt doesn't currently have any.
	args.extend(self.custom_opt.split(' '))

... But didn't revisit this when --tx-broadcast-cmd was added. Will look into fixing it.

Fixed by 46b6d9d. You can now quote arguments, for example --tx-broadcast-cmd "broadcast-tx {tx_hex}".

It might take awhile to get this released in a new version, but for now you could replace the bwt.py file in your plugin directory with updated bwt.py.
