error is needed by all the OpenPGP packages as they return a shared
family of error types.

armor implements OpenPGP armoring. It's very like PEM except:
  a) it includes a CRC24 checksum
  b) PEM values are small (a few KB) and so encoding/pem assumes that
     they fit in memory. Armored data can be very large and so this
     package presents a streaming interface.

The code was (as annotated in the source code) adopted from Tom's
LibCrypt (public domain code, [1]). It was neither optimised for speed
nor were any security features added.

I missed that environment is used during runtime setup,
well before go init() functions run. Implemented os-dependent
runtime.goenvs functions to allow for different unix, plan9 and
windows versions of environment discovery.

A few system call numbers on x86 Linux are
defined in terms of a previous definition,

e.g.,
	#define __NR_timer_create	259
	#define __NR_timer_settime	(__NR_timer_create+1)
	...
	#define __NR_mq_open		277
	#define __NR_mq_unlink		(__NR_mq_open+1)

This change assumes the numbers are sorted
sequentially in the input file.

Regular expressions may now be used in conjuction with full text
search. Godoc will show the first 10000 occurences in the source
code and highlight the respective text segments.

- added new flag -testDir to specify a small directory for testing
  (fast index creation; default = "")

- use new FormatText function to format text and Go source
  code in HTML, supporting multiple kinds of text selections
  simulatenously); this replaces the uses of go/printer
  Stylers

- for now removed currently unused mechanism for identifier-
  specific JS popups (will come back in some form once we
  have type or other useful information)

- various typo fixes and minor cleanups throughout

Missing:
- indexing of non-.go files

The After code is trivially generalisable to provide support

If we don't do this, then when C code calls back to Go code
which panics, we lose space on the scheduler stack.  If that
happens a lot, eventually there is no space left on the
scheduler stack.
