remove unnecessary newline at the start of RPC help descriptions
Summary:
D7184 made it unnecessary to start the description of a help message
with a \n, and fixed most messages accordingly. But it missed a few, and
few more were recently backported without removing the extra newline.
Before:
$ src/bitcoin-cli help importmulti importmulti "requests" ( "options" ) Import addresses/scripts (with private or public keys,...
After:
$ src/bitcoin-cli help importmulti importmulti "requests" ( "options" ) Import addresses/scripts (with private or public keys,...
Test Plan:
pcregrep -M -r 'RPCHelpMan{\n? *"\w+",\n? *"\\n' src/
Check that the result looks good:
src/bitcoin-cli help getblockcount src/bitcoin-cli help dumptxoutset src/bitcoin-cli help generatetodescriptor src/bitcoin-cli help generateblock src/bitcoin-cli help getindexinfo src/bitcoin-cli help addpeeraddress src/bitcoin-cli help importmulti src/bitcoin-cli help importdescriptors src/bitcoin-cli help getaddressinfo src/bitcoin-cli help upgradewallet
