4.7.1 18 AUG 2025 Minor improvements and bug fix release
1. Fix regression in -offset (-o) where it stopped working in Mksquashfs
and Sqfstar.
2. Allow arguments (spaces) in the PAGER environment variable, rather
than just a command name. Also support quoted strings, string
concatenation and backslashes.
3. Don't use a pager to display the help text if the PAGER environment
variable is empty.
4. Add -no-pager option which if specified means a pager won't be used
to display the help text.
5. Add -cols option which specifies the number of columns used to
display the help text. This is useful if output is not to a
terminal.
6. Fix regression in tar file reading, where file exclusion would leak
cache (memory) leading in some cases to Sqfstar hanging.
7. Handle negative dates in tar files (before the start of the epoch of
1970-01-01), and round them up to the start of the epoch.
8. Add --version spelling in addition to -version, as this appears to be
a common mistake.
9. Add missing include files in print_pager.c (Ros Burton).
10. Add missing include file in thread.c (Shiji Yang).
11. Fix BLOCK_READER_THREADS typo in Makefile (Alexandru Ardelean).
