[Intel-gfx] [PATCH v2 maintainer-tools] frob-patch-rank: A little script to batch renaming patch files

The "usage" text should explain it all. I found, in my quilt series
handling endeavours, that I wanted to be able to shift the prefix
numbers of a patch series.

v2: Use heredoc for usage string, fix second example, use mv -i (Jani)

+Usage: $script start end expr
+
+  Frob patches."
+
+  This tiny script renames \"git format-patch\" patches by executing 'expr'
+  on the number that prefix the patch file, but only if the patch file name
+  starts with a number in ['start','end'].
+
+Examples:
+  $ ls *patch
+  0008-Super-patch.patch
+  0009-Mega-patch.patch
+  $ $script 8 9 -7
+  $ ls *patch
+  0001-Super-patch.patch
+  0002-Mega-patch.patch
+
+  $ ls *patch
+  0117-Super-patch.patch
+  0118-Mega-patch.patch
+  $ $script 117 118 +900 -17
+  $ ls *patch
+  1000-Super-patch.patch
+  1001-Mega-patch.patch
