In combination with the thisPub() function, this macro simplifies accessing the public part of a private object struct.
thisPub() asserts this != NULL so the caller does not need to do it.
Introduce a standard pattern for exposing public struct members (as documented in CODING.md) and use it to inline lstSize() which should improve the performance of iterating large lists.
Since many functions in these modules are just thin wrappers of other functions, inline where appropriate.
Remove strLstExistsZ() and strLstInsertZ() since they were only used in tests, where the String version of the function is sufficient.
Move strLstNewSplitSizeZ() to command/help/help.c and remove strLstNewSplitSize(). This function has only ever been used by help and does not seem widely applicable.
The original intention was to enclose complex code in braces but somehow braces got propagated almost everywhere.
Document the standard for braces in switch statements and update the code to reflect the standard.
We use the Z suffix in many functions to indicate that we are expecting a zero-terminated string so make this function conform to the pattern.
As a bonus the new name is a bit shorter, which is a good quality in a commonly-used function.
This has been the policy for some time but due to migration pressure only new functions and refactors have been following this rule. Now it seems sensible to make a clean sweep and move all the comments that have not been moved already (i.e. most of them).
Only obvious typos and gross inaccuracies in the comments have been fixed. For this most part this was a copy and paste operation.
Useless comments, e.g. "New object", were not copied. Even so, there are surely many deficient comments left.
Some rearranging was done where needed and functions were placed in the proper sections, e.g. "Constructors", "Functions", etc.
A few function prototypes were found that not longer had an implementation. These were removed, but there may be more.
The coding document has been updated to reflect this policy, which is not new but has never been documented.
Adding a dummy column which is always set by the P() macro allows a single macro to be used for parameters or no parameters without violating C's prohibition on the {} initializer.
-Wmissing-field-initializers remains disabled because it still gives wildly different results between versions of gcc.
