INSTALL.md: Restore $ as command prompt indicator

We have a notational convention in INSTALL.md, which says this among
others:

> Any line starting with a dollar sign is a command line.
>
>     $ command
>
> The dollar sign indicates the shell prompt and is not to be entered as
> part of the command.

That notation exists to make it clear what is a command line and
what's output from that command line.

 Full verbosity (`make` macro `VERBOSE` or `V`):
 
-    make V=1 test                                  # Unix
-    mms /macro=(V=1) test                          ! OpenVMS

+    $ nmake V=1 test                                 # Windows
 
 Verbosity on test failure (`VERBOSE_FAILURE` or `VF´, Unix example shown):
 
-    make test VF=1
+    $ make test VF=1
 
 Verbosity on failed (sub-)tests only (`VERBOSE_FAILURES_ONLY` or `VFO`):
 
-    make test VFO=1
+    $ make test VFO=1
 
 Verbosity on failed (sub-)tests, in addition progress on succeeded (sub-)tests
 (`VERBOSE_FAILURES_PROGRESS` or `VFP`):
 
-    make test VFP=1
+    $ make test VFP=1
 
 If you want to run just one or a few specific tests, you can use
 the make variable TESTS to specify them, like this:
 
-    make TESTS='test_rsa test_dsa' test            # Unix
-    mms/macro="TESTS=test_rsa test_dsa" test       ! OpenVMS
-    nmake TESTS='test_rsa test_dsa' test           # Windows
+    $ make TESTS='test_rsa test_dsa' test            # Unix
+    $ mms/macro="TESTS=test_rsa test_dsa" test       ! OpenVMS
+    $ nmake TESTS='test_rsa test_dsa' test           # Windows
 
 And of course, you can combine (Unix examples shown):
 
-    make test TESTS='test_rsa test_dsa' VF=1
-    make test TESTS="test_cmp_*" VFO=1
+    $ make test TESTS='test_rsa test_dsa' VF=1
+    $ make test TESTS="test_cmp_*" VFO=1
 
 You can find the list of available tests like this:
 
-    make list-tests                                # Unix
-    mms list-tests                                 ! OpenVMS
-    nmake list-tests                               # Windows
+    $ make list-tests                                # Unix
+    $ mms list-tests                                 ! OpenVMS
+    $ nmake list-tests                               # Windows

 see what other HARNESS_* variables there are.
