Rangi	e596dbfc80	Make failed macro arg expansions non-fatal ... Expanding empty strings is valid but pointless; macro args already skipped doing so, now other `beginExpansion` calls do too. This also fixes failed interpolations (which were already non-fatal) to continue reading characters, not evaluate to their initial '{' character.	2021-04-22 09:59:02 +02:00
Rangi	fe3521c7a4	Switch from parentheses to angle brackets ... `\(` is more likely to be a valid escape sequence in the future (as is `\[`) and `\{` is already taken.	2021-04-20 17:14:21 +02:00
Rangi	637bbbdf43	Support multi-digit macro arguments in parentheses ... This allows access to arguments past \9 without using 'shift'	2021-04-20 17:14:21 +02:00
