 # ADVICE-ON-FAILURE-BEGIN:all
-# It can help to run "make bootstrap", which can resolve many build
-# failures caused by incrementally building from a previously built
-# checkout.
-
-# Failing that, running "make V=1" will cause Make to display the full
-# commands it invokes to build Emacs, which helps to investigate the
-# problem.
+#   You might try to:
+#   - run "make bootstrap", which might fix the problem
+#   - run "make V=1", which displays the full commands invoked by make,
+#     to further investigate the problem
 # ADVICE-ON-FAILURE-END:all
 
 # ADVICE-ON-FAILURE-BEGIN:bootstrap
-# If "make bootstrap" failed, try running "make extraclean" and then
-# "make bootstrap" again.  If that still fails and you are building
-# Emacs from a repository checkout, run "git clean -fdx" and retry
-# "make bootstrap".  Otherwise, please report a bug by sending email
-# to bug-gnu-emacs@gnu.org.
+#   You might try to:
+#   - run "git clean -fdx" and run "make bootstrap" again, which might
+#     fix the problem
+#     !BEWARE! "git clean -fdx" deletes all files that are not under
+#     !BEWARE! version control, which means that all changes to such
+#     !BEWARE! files will be lost and cannot be restored later
