* po: In the Makefiles, enable --quiet by default when possible.Bruno Haible2023-03-1434-289/+347
| | | | | | | | | | | | | | | | | | | | | | | | | This is possible because msgmerge became faster - through an index-based fuzzy search (msgl-fsearch.c) in 2006, - through OpenMP parallelization in 2006, - through processor speedups over the years. The only case where msgmerge is still slow is when a compendium is in use.
