+# AM_PROG_INSTALL_STRIP
+# ---------------------
+# One issue with vendor 'install' (even GNU) is that you can't
 # specify the program used to strip binaries.  This is especially
 # annoying in cross-compiling environments, where the build's strip
 # is unlikely to handle the host's binaries.
 # Fortunately install-sh will honor a STRIPPROG variable, so we
-# always use install-sh in `make install-strip', and initialize
+# always use install-sh in "make install-strip", and initialize
 # STRIPPROG with the value of the STRIP variable (set by the user).
