# generate a form FORM containing TEXT
# TEXT can contain newlines (final newline usually undesirable)
# if FORM not specified, generates Arg0 Arg1 Arg2 in sequence
-# character set is SPC 0-9 a-f + * (`*' glyph is `=/=').
+# character set is SPC 0-9 a-f + *
#
# We generate a physical indication of which commit was used.
#
#
# We can generate these forms:
#
+# In each case:
+# if tree is dirty, * is suffixed or prefixed to count or commitid
+# if tree has untracked files, + is added
+# (where it is added depends on the Form; in any case it does not
+# change the size, but steals space from digits)
+#
# Small3:
# Small4:
# Small5:
# git rev-list --first-parent --count HEAD
# typically 3-4 characters but we allow for up to 6
# padded with zeroes; if too long we reduce mod 10^n
-# eg
-# Small4 1070
-# If tree is dirty, + or * is suffixed, reducing number of
-# digits by 1.
+# eg if the count is 123456
+# Small5 3456*
+# Small8 __123456 (where _ are spaces)
#
# Small4S:
-# Small6S:
-# Small8S:
+# Small6S: Small6T:
+# Small8S: Small9T:
# Small10S:
-# same but split into two lines eg
-# Small4S 10
-# 70
+# same but split into two lines (S) or three lines (T) eg
+# Small4S 45 Small6T _3
+# 6* 45
+# 6*
#
# Git4 Git4S
-# Git6 Git6S
+# Git6 Git6S Git6T
# Git8 Git8S
+# Git9 Git9T
# Git10 Git10S
# git-rev-parse HEAD (prefix of requested length)
-# eg
-# Git6 82f2a2
-# If tree is dirty, + or * is suffixed to commitid,
-# reducing number of hex digits by 1.
+# eg if the commitid is abcdef0123...
+# Git5 abcd*
# Full3
# Full4
# git-rev-list --first-parent --count HEAD
# git-rev-parse HEAD
# eg
-# Full6 1070
-# 82f2a2
-# If tree is dirty, + or * is suffixed to count (but not to
-# commitid) reducing number of digits by 1.
+# Full6 abcdef Full8 abcdef01
+# 23456* _123456*
+#
+# Full6T
+# Full9T
+# Full12T
+# Full15T
+# as Full but commit is split over two lines
+# for a 3-line message; eg
+# Full9T abc
