Revision 1.10, Mon Jan 20 10:37:15 2020 UTC (4 years, 3 months ago) by schwarze
Branch: MAIN
Changes since 1.9: +13 -2 lines
Make the code more readable by introducing
symbolic constants for tagging priorities.
This review also made me find a minor bug: do not upgrade
TAG_FALLBACK to TAG_WEAK when there is trailing whitespace.
