Message:

Better source unifier

• now it is called scripts/unify-sources.sh
• replaces each tab with 8 spaces
• remove trailing spaces (and tabs)
• warnings on long lines (i.e. on lines that are more than 80 characters)
• the standard file header now turns off the space-to-tab replacement in Emacs

File:

• scripts/unify-sources.sh (moved) (moved from scripts/update-copyright-header.sh) (2 diffs)

scripts/unify-sources.sh
